While death rates for prostate cancer have been decreasing in most developed countries, mortality rates are rising in some European and Asian countries such as South Korea, China and Russia. A non-invasive way of removing prostate cancer tumors is now available in the United States with the help of robotic technology.

The University of Southern California is the first academic medical center in the U.S. to perform this type of procedure.

Brett Lindsay knows he made history when he underwent a procedure known as robotic high intensity focused ultrasound, or HIFU.

The U.S. Food and Drug Administration recently approved the procedure even though it’s been used in other countries to treat prostate cancer for about 10 years. Traditional prostate cancer treatments include either removing the entire gland or radiation, which will affect the quality of life for patients even if the cancer is removed, said Inderbir Gill, lead urologist at the University of Southern California Institute of Urology at Keck Medicine of USC.

“The nerves that are lying right next to the prostate that are responsible for erections, the sphincter that’s lying right next to the prostate that is responsible for urinary continence, they get compromised. So, yes, you take care of the cancer, but you significantly impact the person’s quality of life,” Gill said.

With HIFU, only the cancer is identified, targeted and destroyed. The HIFU procedure is an outpatient procedure, said Robert Barnett of SonaCare Medical, one of the manufacturers of the technology.

“Here we’re taking ultrasound energy off of a concave or bowl-like surface and bringing that to a focal point, and at that point we have tremendous heat generated and we can destroy tissue,” Barnett said.

HIFU devices are used in Western Europe, Latin America and some Asian countries, but not so much in developing countries.

“I think in the Third World if you will, in developing countries, it’s a financial thing. Those countries certainly don’t have the resources to commit to health care. Their focus is more on preventing infectious disease,” Barnett said.

But he said that, looking at the global cost of treating prostate cancer, HIFU technology is less costly than radiation and it can easily be implemented in an unsophisticated medical setting.

Gill said having the HIFU procedure at an academic medical center will allow them to further research the outcomes of HIFU procedures, minimize any side effects and advance the technology.

The objective is “to figure out what molecular and genetic markers predict HIFU success, HIFU failure. Which patients are the best candidates for it? How do we not overtreat cancer? How do we not undertreat cancer?” Gill said.
